RECORDER.

SPECIFICATION forming part oi Letters Patent No. 349,767, datedSeptember 28, 1886.

Application iized July 17, 1885.

To all whom, it may concern:

30 it known that we, AUGUSTUS TORREY, a citizen of the United States,residing at Detroit, in the county of IVayne and State of Michigan, andDENNIS J. Casnv, a citizen of the United States, residing at Cylon, inthe county of St. Croix, State of XVisconsin, have jointly inventedcertain new and useful Improvements in Passengerltecorders, and we dohereby declare that the same are fully described in thefollowingspecilication,and illustrated in the accompanying drawings.

This invention relates to improvements in passenger-recorders, for thepurpose of auto matically recording the number of passengers going in orout of railroad-ears, as well as antomatically recording the number ofmiles or the time that the passengers have traveled in such conveyances.

The invention is adapted for use wherever it is requisite or desirableto automatically record the number of persons going in or out of anypublic conveyances or public places.

Letters Patent No. 315,355 were granted to us April 7, 1885, for apassengerarecorder, in which, combined with movable treadles, we usedelectro-maguets and an electric battery l'or recording upon a strip ofpaper, by means of pencils actuated by the electro-magnets, the numberof passengers going in or out of the car. In said patent the paperribbon was drawn from one roller to another by means of clock workmechanism, and the markers or pencils were operated electrically. In ourpresent invention we use movable treadles arranged on top of stationarysteps and connected by means of wires to an electric battery, so as toclose the circuit for every time the movable treadle is depressed, inthe same manner as described in our previous patent, and we also use areel of paper, from which the ribbon is drawn by clock-work mechanism toa second roller but instead of effecting the marking 011 the paperribbon by electrical means, as described in our previous patent, we doit by electrochemical meansthat is, the ribbon is made to pass throughor be soaked in a solution of lerrocyanide of potassium, and, afterbeing moistened, a number of metal (steel or or iron) markers are heldlightly in contact Serial No. 171,856.

with it, such markers being connected by wires to a battery, the otherpole of which is connected to the metal drum or roller on which thepaper ribbon is guided after it has been moistenedthat is, one side ofthe paper lies in contact with such metal drum in the circuit, and theother side of it touches the metal markers or pencils, also in thecircuit. Each movable treadle on the car is connected by a wire to itscorresponding marker and the battery, and normally the circuit open forall pencils and their treadles. If any treadle is depressed, theelectrode on it will come in metallic connection with the electrode onthe stationary step below, thus automatically clos ing the circuit forthat particular step, and causing the formation of some Prussian blue onthe paper ribbon where the metal pencil or marker corresponding to suchstep in the closed circuit touches the paper, and thus pro ducing a markon the ribbon as it is being fed to the receiving-roller, to indicatethat a person did go up or down that particular step. In connection withthis device we use a clock mechanism for feeding the paper ribbon fromthe delivery roller or reel to the receiving roller, and an electricalregulating device to regulate the feed 01' the paper, so that the lattershall be moved comparatively slow when no marking is being madethat is,when no trcadle is depressed and with an illcreased speed when themarking takes place. Each trcadle has its corresponding needle ormarker,and in addition to such treadle-markers, we use one additionalneedle also held in contact with the moistened paper and connected by awire in the circuit which is broken and closed by means of pins orprojections 0n adisk connected to the clock 1nechanism,so as to producea mark on the ribbon at stated intervals 0 ICO up the clock mechanismthat feeds the paper ribbon we use an intermittent current-breaker andan electro-magnet in the circuit,the armature of which is provided witha pawl or lever of any suitable construction to actuate a ratchet-wheelon the winding mechanism on the clock-work.

Our invention is carried out as follows, reference being had to theaccompanying drawings, in which- Figure 1 represents a side elevation ofthe improved passenger recorder. Fig. 2 is a plan view of the vesselcontaining the chem-- ical liquid through which the ribbon is made topass, showing also the metal guide-roller and the markers or pencils.Fig. 3 is a front elevation of Fig. 2. Fig. 4 represents an enlargedcross-section on the line A B in Fig. 1, showing the automaticfeed-regulating mechanism for the receiving-roller on which the ribbonis wound after being marked. Fig. 5 represents the manner of connectinga step on the car with the battery elect-ro-magnet and needle; and Fig.6 represents a plan view of the ribbon with the treadle-marks andtimemarks made thereon.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In Fig. 1, (t represents the delivery roller,

.on which the ribbon I) is wound, and from which it is carried to thereceiving-roller c after being marked. Both rollers a and c are providedwith shafts supported looselyin stationary bearings, as usual. Theroller 0 has attached to it the gear-wheel c, the teeth of which engagein the teeth of pinion (Z, which is set in motion by clock-work,hereinafter to be more fully described.

6 is a vessel or receptacle of glass or other suitable material,containing an aqueous so lution of ferro-cyanide of potassium. 'WVithinthe vessel 0, near its bottom, is located in suitable bearings theloosely-journaled guiderollers f. To the outside of vessel 6, and nearits upper end, is secured the needle carrying frame G, provided withslotted sides G G, in which is supported the ends of the roller H, thelatter being made to yield in said slotted sides G G against theinfluence of springs h h to permit the paper ribbon to be insertedbetween roller H and the inner ends of metal needles or markers 9 g g,which are guided in frame G and caused to press lightly against thepaper ribbon, resting against the roller H, by the influence of springsg g g, as shown. The frame G is made of vulcanized rubber or othernon-conductive material. The drum or roller H is made of copper or otherconductive material, and the needles or markers 1 g are made of steel orironl i represents one of the stationary steps, and k is the movabletreadle or cover hinged to it and normally raised above it by means ofspring or springs Z in the same manner as described in our previouspatent.

t" and k are the electrodes, respectively, on step t and movable treadle7;, as usual, such electrodes being held apart by spring Z when nopressure is brought to bear on treadle It.

at is a battery, having one of its poles (the one marked in Fig. 5)connected to stepelectrode 1" by wire :0, and the other pole (markedconnected to one end of electromagnet N by wire 00. From the other endof eleetro-magnet N leads the wire as to the insulated metal roller H.From the electrode 7con the yielding step or treadle leads a wire, 00*,to its corresponding needle or marker 9 in the series. It will thus beseen that the current is normally broken, and it is closed only when anyone of the electrodes 70 is brought into contact with its correspondingelectrode, i, causing a blue mark to be made upon the paper I),immediately under the point of the needle or marker 9 which is in theclosed circuit, owing to the formation of some Prussian blue by theaction of the current upon the needie and moistened paper.

The feed-pinion d, for feeding the paper I), is made to revolve slowlyat all times except when a treadle is depressed and the current. closed,and this is automatically accomplished by the following means: The wheeld is loosely .journaled on the hollow sleeve 0, which is rotated with aslow constant motion by means of any suitable clock mechanism, 0, asshown in Fig. 4 of the drawings. \Vithin the sleeve 0 is located thespindle p, which is free to turn within sleeve 0, and, is also set in aconstant rotary motion by means of suitable clock mechanism, 1?, (shownin Fig. 4,)by which it is moved with an increased speed as compared withsleeve 0.

Any suitable clock mechanism may be used for direction of the axis ofspindle pand sleex e 0 by means of the collars or flanges 0 1), as shownin said Fig. 4.

q q q are pins passing loosely through the gear (I, such pins havingsecured to one of their ends the friction-ring O, which is normally heldin contact with the tapering friction-wheel O by means of coiled springsq q, 7

located between gear (I and ring 0, and surrounding the guide-pins (l q,as shown in Fig. 51, and when the ring 0 and friction-wheel O are soheld together the gear d is turned comparatively slowly, owing to itsbeing temporarily locked to the slowly-rotating sleeve 0. On the otherside of wheel d is secured to pins q q another friction-ring, 1?, thatis normally held disengaged from friction-wheel P by the influence ofthe springs q q, as shown. To the extreme left ends of pins q q, Fig. 4,is so cured the armature Q, which, when the current is closed, isattracted toward the magnetized cores n a in electro-magnet N, therebycausing the ring 0' to be disengaged from the slowlyrotating wheel 0,and the ring I? to be brought in contact with the more-quickly rotatingfriction-wheel I, causing the wheel (I to rotate quickly with the samespeed as wheel 1 and its spindle'p as long as the circuit is closed. Inthis manner the feed of the ribbon is automatically regulated to feedslowly when no marking takes place, so as not to use up any more ribbonthan is necessary, and with a quicker motion when the marking takesplace, so as to leave proper spaces between the marks made by theneedles. It is also desirable to indicate on the ribbon the time whenthe marks were being made, and for this purpose we secure to hollowspindle 0 a disk, R, provided with a number of metal projections orpins, r r, so arranged upon the side or face of disk R that each one ofthem shall pass a stationary point every three minutes (more or less) asthe disk It is rotated. The pins 0' r are made to operate a suitablecircuit-closer, S, on which the poles are normally held apart by meansof a spring or equivalent device. One of the poles of circuit-closer Sisconnected by means of wire to" to the +-pole of battery m, the otherpole being connected by means of wire a to time marker or needle T,located in frame G, and held in contact with the paper moving over drumII by means ofspring t, precisely like the step-markers gg and theirsprings g g. It will thus be seen that the current is closed and made topass through pencil T, so as to produce a time-mark on the paper everytime a pin, r, passes by the circuit-closer b.

As before stated the clock mechanism for driving sleeve 0 and spindle 1)may be of any well-known construction. It may be wound up by hand, asusual, although we prefer to combine with it an electrical self-winder,as follows: To the wheel R we attach a number of metal pins, 1" 1',(shown in Fig. 4,) the free ends of which are made to project somewhatbeyond the ends of pins 0- 1, that operate the circuit-closer S. As thewheel R rotates the pins r 1- come in contact with a suitablecircuit-closer, U, on which the poles are normally held apart by meansof a spring or equivalent device. The poles on circuit-closer U areconnected by wires :0 and to a battery, M, (shown in Figs. 1 and 5,)with an electromagnet, V, located in the circuit.

\Ve have shown in the drawings a separate battery for the winding-updevice; but, if so desired, the wires from circuit-closer U may beconnected to positive and negative poles of the main battery m withoutdeparting from the essence of our invention.

V is a vibratory armature on electromagnet V, that will be caused torock for every time the current from battery M is elosed that is,whenever a pin, 1', passes by the circuit-closer U. The vibratoryarmature Y may be connected to the spring-barrel on the clock mechanismon sleeve 0 and spindle p by means of a pawl and ratchet or otherwellknown intermediate connecting mechanism, (which. latter is, however,not shown in the drawings,) so as to cause the clock mechanism fordriving pinion d to be intermittingly wound up from time to timepreferably a little faster than it runs down.

In Fig. 6 is represented a plan view of the paper ribbon I) after it hasreceived its treadlemarks and time-marks, as above described, and insaid figure, Z Z represent the intermittent time-marks made by marker Tfor every time the circuit is closed by the circuit-closer S and pins 0'on wheel The marks T T are the treadleanarks caused by closing thecircuit at the electrodes on step and treadle, their positions on theribbon showing whether a passenger has gone in or out of the car, orgone partially up or down the steps without going into the car or goingoff it, precisely in the same manner as shown and described in ourPatent No. 315,855.

Having thus fully described the nature, construction, and operation ofour invention, we wish to secure by Letters Patent and claim-- 1.
